Professional Grade High-Resolution QR Codes

SVG (Scalable Vector Graphics) is the best format for printing because it scales to any size without losing quality. PDF is also excellent for print. PNG works for digital use and small prints but will pixelate if enlarged significantly. QRLynx offers SVG and PDF downloads on Starter+ plans and above.

Yes — if you download in SVG or PDF format. These are vector formats that contain mathematical paths rather than pixels, so they remain perfectly sharp at any size. PNG and JPG are raster formats that will become pixelated when enlarged beyond their original dimensions. Always use SVG for print.

For professional printing, use 300 DPI minimum. For large-format printing (posters, banners), 150 DPI is sufficient because viewing distance is greater. For billboards, even 72 DPI works at scale. The best approach is to download your QR code as SVG — it is resolution-independent and will print perfectly at any DPI.

SVG is a vector format — it uses mathematical shapes that scale infinitely without quality loss. Ideal for print at any size. PNG is a raster format — it is made of pixels and has a fixed resolution. PNG works for screens and small prints but will look blurry when enlarged for posters or banners. SVG files are also typically smaller in file size.

Yes. QRLynx offers transparent background downloads in PNG format. This lets you place the QR code on any colored background, photograph, or design without a white box around it. Ensure there is still adequate contrast between the QR code and the background for reliable scanning.

The minimum scannable size is about 1 cm x 1 cm (0.4 inches) for a simple URL code scanned from close range. For practical use, 2 cm x 2 cm is the recommended minimum. The 10:1 rule applies: the scanning distance should not exceed 10 times the QR code width. A 3 cm code works up to 30 cm away.

PNG and JPG downloads are free on all plans. SVG and PDF vector downloads are available on Starter+ ($7/month) and higher plans. The vector formats are essential for professional printing — they ensure your QR code is crisp at any size without pixelation.

Only if it was created as a vector format (SVG or PDF). Vector QR codes can be scaled to billboard size without any quality loss. Raster formats (PNG, JPG) will become pixelated when enlarged. If you only have a PNG, recreate the QR code and download it as SVG for print use.

In QRLynx, create your QR code, customize the design, then click the Download button. Select SVG or PDF from the format options. These vector formats can be opened in Adobe Illustrator, Inkscape, Affinity Designer, and most professional design and print software. SVG is also supported by Canva and Figma.

For billboards viewed from 5+ meters away, even 72-100 DPI is sufficient because the viewing distance is so large. A QR code on a billboard should be at least 50 cm x 50 cm (20 inches) for reliable scanning from 5 meters. Always download as SVG so the print shop can scale it to exact dimensions without quality concerns.

Always download your QR code in SVG or PDF format for printing. Never screenshot a QR code from your screen — this creates a low-resolution image. If you must use PNG, download it at the largest available size and do not enlarge it in your design software. Set your download size to at least 1000x1000 pixels for PNG.

The 10:1 rule states that the maximum scanning distance is approximately 10 times the width of the QR code. A 3 cm QR code can be scanned from up to 30 cm away. A 10 cm QR code works from about 1 meter. A 50 cm billboard QR code scans from roughly 5 meters. This ratio applies under good lighting conditions.
